English original: Nvidia’s $4 Billion Secret: Why Photonics Is the Next AI Gold Rush /posts/nvidia-photonics-ai-gold-rush/ 40억달러라는 신호 2026년 3월 2일, 엔비디아는 조금 이상한 행동을 했다. 새 GPU를 발표한 것도, AI 스타트업을 인수한 것도 아니다. 대신 광학(optics) 기업 두 곳에 총 40억달러를 투자했다. Lumentum에 20억달러 Coherent에 20억달러 두 회사는 칩을 만들지 않는다. 모델을 학습시키지도 않는다. 그들이 만드는 건 한 가지다. 빛으로 데이터를 옮기는 부품(광학 컴포넌트). “왜 AI 왕국의 핵심 기업이 레이저에 돈을 넣지?” ...
The $4 Billion Signal On March 2, 2026, Nvidia did something unusual. It didn’t announce a new GPU. It didn’t acquire an AI startup.
